The author studied about the distribution and change of terrestrial insects in Mt. Naeyoen, Pohang, since 1997, which was limited to listing the species. It was focused on the temporal distribution of the long-term faunal changes over 9 years, from 5 different locations, each of which was classified as inland or shore (centering on the top of mountain), The 5 location were further divided into the eastern side, which is fully affected by sea wind, and the western side, which is not. The results are as follows. 1. It was founded insect of 14 orders, 67 families and 168 species, of which is 122 species was added newly to the 11 orders, 33 families and 82 species identified by the report from the Ministry of Environment in 1997. The 122 additional species include 11 Odonata, 1 Microcoryphia, 2 Mantodea, 8 Orthoptera, 18 Hemiptera, 3 Homoptera, 19 Coleoptera, 11 Hymenoptera, 12 Diptera and 37 Lepidoptera. 2. As for the vertical distribution in inland, Aelia fieberi and Graphosoma rubrolineatum were found up to 200m and Anapodisma beybienkoi up to 930m in inland, on the contrary, in shore, Anoplocnemis dallasi, Haslundichilis viridis, Sericinus montela and Libythea celtis were found up to 200m and Eurema hecabe up to 400m. However, above 400m, there was no big difference of species occurred in inland and shore. 3. In terms of biodiversity, the inland showed diversity index of 4.766, richness index of 21.949 and evenness index of 0.936, whereas the shore had diversity index of 4.734, richness index of 22.516 and evenness index 0.927. For dominance index, both inland and shore had 0.052. In summary, the inland had higher diversity index and evenness index than the shore had, while the shore had higher richness index than the inland had. 4. For community similarity, that of (S2-S4) had the highest value and was followed by that of (S2-S5), (S1-S5), (S4-S5), (S2-S3), (S3-S5), (S1-S2), (S3-S4), and (S1-S4) in that order. That of (S1-S3) had the least community similarity, and percent similarity was 78%. 5. Since Aelia Fieberi, Graphcecma rubrolineatum and Anapodisma beybienkoi inhabit inland, it was believed they were vulnerable to salt. On the contrary, it is predicted the inhabitants of shores such as Anoplocnemis dallasi, Haslundichilis viridis, Sericinus montela and Libythea celtis and Eurema hecabe to be more tolerable to salt. It is believed that these insects inhabited in the shore could be used as indicator species for salt, and further studies will be necessary on this.
